What are the dangers of drugs to help me ovulate?

Fertility drugs such as clomiphene citrate tablets (clomid) and hCG injections work by increasing your chances of ovulating (releasing eggs from your ovary). The number of eggs that you release cannot be controlled precisely, so there is always a chance that several eggs may be released at once increasing your risk of multiple pregnancy (twins, triplets or more). Furthermore, there is a risk, particularly with injections, of ''ovarian hyperstimulation'', a condition where the ovaries grow very large, with cysts in them, and you can become dangerously sick with abdominal pain and dehydration (sometimes needing hospital admission); this condition if serious needs expert treatment. On a different note, There is no firm evidence, however, of a link between IVF treatments and cancer of the ovary.
